The exporter transcodes ADV.wmv and S00A.wmv to Ogg Theora and records the exact
ffmpeg command in the manifest, per MISSION §6, so a modder who dislikes the
quality re-runs one line rather than reverse-engineering what was done.
Quality was MEASURED, not judged: SSIM against the decoded source over a 10 s
sample is 0.9863 / 0.9896 / 0.9924 at -q:v 6 / 8 / 10, and at 200 % zoom on the
reel's hardest case -- fine serif text and soft gradients over near-black, where
Theora breaks first -- q8 is indistinguishable. So MISSION §6's permitted
FFmpeg-GDExtension fallback is NOT needed and is NOT being proposed. No new
runtime dependency.
-ac 2 because the source is 6-channel WMA Pro; that downmix is a decision, so it
lives in the recorded command rather than in prose.
Encoding is cached on a .cmd sidecar holding the command and the source size --
any change to either re-encodes. export/ is still regenerated wholesale; this is
derived state validating derived state, not a hand-edit, and without it every
re-export pays ~4 minutes to produce a byte-identical file.
The player renders INTO the design SubViewport. Parenting it to the Boot node
played the movie to the window instead, and every captured frame came out black
-- which is worth more than a capture-bug note: a movie outside the 1280x720
design space is outside the coordinate system every screen is expressed in.
(A) skips a movie, because Q9 measured that (title at 57 s vs a 193 s baseline).
NOT VERIFIED, and stated as such: audible playback. This container has no audio
device and Godot falls back to the dummy driver. The Vorbis stream exists, is
2-channel and decodes; whether Godot emits it is unconfirmed.
